ENVENTOR AZF/Z'i? H. 5170627701? HY I 4 f WCM ATTURNEY ti l 9 H d ld i arpp To all who us may concern:

lie it lnioivn that .l, .r lnvirr ltlh hlnlonntannsin a citizen oi? theUnited titatea residing at Uahland u ldtate oli Uslr'uhornia haveinvented certain new and uselful improvements in Vehicle l l heels oiwhich the tollovving a. specilication. 4

'llhis invention relates to improvements in vehicle Wheels and moreparticularly to a new and novel structure tor connecting the hub andrini.

The principal object of the present inven tion is to provide improvedmeans for rendering the vehicle rinl deinountahle. This object isaccomplished by providing a corrugated vveh between the huh and rimWhich is circunaterentially expansible, and which cooperates with theinside of the rim to hold the latter in place Another object of theinvention is to so arrange the hub structure that the Web is expandedand contract ed by the use of a single m A further object of theinvention is to term the vveb in such a manner as to provide thegreatest possible strength therein with the least possible Weight, thestrength heing uniitorinly disposed from the hub to the rim.

l l 'ith these and other ohjects in view, the invention consists oicertain novel features out construction colnhinatio-ns and arrangeinents cl? par hereinaihter described and more specifically pointed outin the append ed claims; it being understood that changes in term,proportion, sine and minor details 'ol construction Within the scope of,the 'clanns may he resorted to Without departing- I ironi the spirit oithe inven. ion orsacrilicint anv of the advantages thereof} Referring tothe drawings ltorniing a part out the specification,

'llhe 'huh consists out the cylindrical por" tion lroin'ivhich entendsthe coanial pol tion that enterhallp threaded and enl he latter has anannular shoulder adjacent the open end. While the o aposite end isheiragonal lor en gageinent with a, suitable Wrench.

Slidahly mounted on the cylindrical huh portion G is an annular ring 9the peripheral face of "which is conical and which is provided at oneend with the inwardly entendis adapted to ahut against the shoulder 8.The huh cap is also provided With a radial. flange so extending outWardly from the shoulder 8. A ring hi fastened 011 the outside of ring 9and this ring has an inwardly extending flanged portion 22 which engagesflange am the face opposite shoulder 8. In this Way the coni cal inemher9 is constrained to move airially When the huh cap is turned The WGlJ orspolre structure l0 oi luv Wheel which forms the principal part or theinvention hent troni a. single sheet oat metal and consists oi series ofradial corrugations. These corrugations adjacent the huh, are curvedalmost at an angle oi 'lhU Whileadjaceut the run or the outer peripherv, adjacent corru -ations make a lesser an gle with each other. in each.corrugation are provided cut-out portions ll which are substantiallytriangular in maps, the point being adjacent the huh Where the greateststrength is required and the base heinp; adjacent the rim Where the dishcontains the greater amount or metal and Where the least bending stresstalres place.

The manner of corrugating the dish such that strength is secured Whereneeded for the deep substantially parallel-sided col--- rugationadjacent the huh giving the greatest reinforcement at this point Thecenter of the corrugated weh termed as above described is provided witha tapering opening that is adapted to seat on the conical outer surlaceof ring 9 While the outer peripheryofthe web is curved or provided witha concave groove that is adapted to engage a similarly shaped convexsurface on the inner periphery of the Qt Hi its On the outsidecylindrical surface of the hub cap is provided screw threads that areadapted to be engaged by a nut 24 this nut being provided with anannular shoulder 25 which engages a disk 13, the outer edge of which iscurved to engage the corrugations of the disk 10.

The hub is also provided with a radial flange 27 the outer edge of whichis provided with corrugations that are adapted to co-act with thecorrugations of the web 10, these corrugations being of such shape thatthey form the drive connection between the hub and web 10. I

In use the corrugated disk 10 is placed over the hub 6 and the small endof ring 9 is engaged in the central opening of the disk. At the sametime the interior threaded portion of the hub cap engages the threadedportion of the hub so that when the hub cap is turned on to thesethreads,'

the conical ring is forced into the opening of the corrugated diskthereby expanding the latter. This expansion takes place due to the factthat the metal of the disk bends parallel to the corrugations andequally around the periphery so that the periphery is forced against theinside of the vehicle rim 1%.

VVhcn the outer edge of the corrugations comes in contact with the rimand seats tightly thereon, the rim itself acts as a tie to the outeredge of the disk and the whole becomes very rigid. It will be noted thatthe disk is formed so that one face is in a plane at right angles to theaxis of rotation while the other side is concave as viewed from theoutside. This construction not only is mechanically correct to resistthe outward thrust exerted by the axle, but is also that which the metalof the disk will assume without any stretching.

New to remove the rim 1% and tire carried thereby, it is only necessaryto slightly slacken off the nut 52% and then to turn the hub cap untilthe conical ring 9 is moved from under the central'opening of disk 10.This allows the latter to contract until the outer edge takes theposition shown in dotted outlines at 15, enabling the rim to be slippedofl' laterally and a new one placed in position.

All the spokes or uncut portions of the disk adjacent the ground arestressed when there is an axial thrust exerted against the center of thewheel. This is the case even though alternate spokes are on oppositesides of the convex portion of the rim because the stress is carriedacross the latter through the connecting parts 30.

While I have shown the preferred em bodiment of my invention, it will beunderstood that chan ee within the scope of the hub forcircumfercinially expanding against said rim.
